HEEL-REMOVING MACHINE.

Specification of Letters Patent.

Patented May 15 19117.

Application filed September 5, 1916. Serial No. 118,537.

To all whom it may concern Be it known that I, Pnnnr Bunnies, a citizenof the United States, residing at Boise, in the county of Ada and Stateof Idaho, have invented certain new and useful Improvements inHeel-Removing Maciines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to heel removing machines and is designedparticularly for cutting oft the heels of boots or shoes ready for beingreplaced by the new heel of leather or rubber as desired.

The object of my invention is to make a clean, clear cut through theheel in such a manner as to leave any desired portion of the old heelremaining in a true level condition for the reception of the new heel tobe placed thereon.

A further object of my invention is to insure that no part of the heelor shoe will be touched by the machine except where the knife does itswork of cutting through the heel either between any of the layers ofleather forming the heel or the knives may be directed to out directlythrough one of the layers of leather if so desired.

Other objects and advantages will be hereinafter set forth in thefollowing specification taken in connection with the accompanyingdrawings which are made a part of this application and in which,

Figure 1 shows my hand controlled machine complete ready for use.

Fig. 2 shows a reverse side of the machine shown in Fig. 1.

Fig. 3 is a sectional view of the knife guides and showing a section ofone of the knives.

Fig. 4 shows one form of foot controlled machine, while Fig. 5 showsanother form of foot controlled machine wherein both the upper and lowerknives are operated.

In order to conveniently refer to the various parts of my invention andcooperation accessoriesnumerals will be employed, the same numberapplying to a corresponding part throughout the several views.

In materializing my invention I provide a suitable base 1 of anypreferred construction upon which I erect the supporting standards 2 inany desired manner in which a stationary knife 3 is mounted and a movable knife l is also arranged, though it is obvious that both knives maybe made movable as shown in Fig. 5 of the drawings. The cuttingstandards 2 are more clearly shown in Fig. 8 of the drawings wherein itwill be observed that each guide on its inner side is provided with agroove to receive the stationary or movable knife members as the casemay be.

The upper ends of the standards are connected together in any suitablemanner as by the cross bar 5 or equivalent means. The lower movableknife is provided with a shank or stem 6 which may be formed upon one orboth edges with a rack bar or teeth 7 designed to cooperate with thecontrolling pinion 8 to which is secured the lever or crank member 9whereby the knife may be readily raised or lowered incident to the useof the machine. The movable knife 4:, therefore, may be caused tocooperate with the stationary knife 3 in the manner above described.

In Fig. 5 I have shown that the upper knife 3 may be made movable sothat it can be raised and lowered in the guiding members 2 by means ofthe controlling arm or bar 10 which is provided on its upper edge with aplurality of teeth 11, thereby forming it into a cog bar designed tocooperate with the pinion 12 mounted in any suitable mannor as upon theaxle or shaft 13 properly journaled and held in place by an extension1-l of the standards 2 or equivalent means.

The pinion 12 is also placed in mesh with the teeth 15 upon thecontiguous side of the rack bar 6, and since the rack bar 6 is alsoprovided with teeth on its opposite edge as before stated the said baris thus disposed in cooperation with the pinion 8.

In order to control the lower cutting blade by foot power I provide acontrolling bar or rod 16 suitably mounted in a vertical position uponthe standard 2 and having upon its lower end a suitable pedal or member17 to be engaged by the foot of the operator and it follows that whenthe bar 16 is thus forced downward by the foot of the operator it willcause the upper and lower knife to be moved simultaneously toward eachother and when the foot pressure is removed the compression spring 18will cause the bar 16 to be elevated and incidentally raise the upperblade and depress the lower blade, thus leaving the cutting bladesnormally separated from each other ready for the reception of the nextheel to be removed.

It will be readily understood that the bar 16 is to be mounted so thatit can have a free longitudinal movement and thereby op erate the pinionS causing said pinion to act upon the rack bar or shank 6 of the knife 4and it is obvious that when the rack bar 6 is thus forced upward it willact upon the pinion 12 in such a manner as to cause the rack bar 10 tobe moved downward bringing with it the upper knife 3 properly mountedfor that purpose. if preferred the foot controlling bar or rod 16 may beemployed to act upon the lower knife only, in which case the upper knifeismade stationary and the tooth bar 10 may be wholly dispensed with. Thecompression spring 18 will obviously restore the lower blade to itsnormally lowered position ready for acting upon the next heel.

Obviously the various" elements of my invention may be made in anydesired manner and properly assembled as shown, whereby a reliablyefficient heel removing machine is formed so that the heel of a boot orshoe may be very quickly and cleanly cut away including the cleanseverance of all nails, pegs or the like, thus leaving the remainingportion of the heel in a true cleanly cut condition ready for thereception of the new heel to be added.

It will be found in practice that my heel removing machine will thusreliably perform its office and will result in a great saving of bothtime and labor in the work of V removing old heels and preparing fortheir replacement with new heels of .leather or rubber as preferred.

While I have described the preferred combination and construction ofparts deemed necessary in materializing my invention I wish tocomprehend in this application all substantial equivalents andsubstitutes which may be considered as falling fairly in the scope of myinvention.

Having thus described my invention what I claim and desire to secure byLetters-Patent 1s V 1. A heel removing machine comprising a base,supporting standards projecting upwardly from the base, a pair of knivesvertically movable in said standards, a rack bar depending from theupper knife, a shank projecting from the lower knife and provided in itsopposite side edges with rack teeth, a pinion di posed between saidshank and rack bar, another pinion meshing with the opposite side edgeof the shank, and means for rotating said last-namedpinion to cause saidknives to reciprocate to and from each other.

2. A heel removing machine comprising a base, standards projectingupwardly from the base, a pair of knives vertically movable in saidstandards, a rack bar depending from the upper knife, a shank dependingfrom the lower knife and provided in its opposite side edgeswith rackteeth, a pinion interposed between said shank and rack bar, another rackbar disposed adjacent said shank, a pinion interposed between said lastnamed rack bar and the shank, the standard adjacent the last-named rackbar being provided with an elongated recess, a collar mounted upon saidrack bar and movable in said recess, and an expansion spring mountedupon the rack bar between said collar and the bottom of the recess,whereby the knives will be returned to their normal position afteractuation.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
